Greek Cross
Greek Cross: a composite plane figure made of a square with side 2.6 cm, joined with a square with side 2.6 cm, joined with a square with side 2.6 cm, joined with a square with side 2.6 cm, joined with a square with side 2.6 cm. It is a classic primary school geometry problem (“Orthogonal Profiles”). The net area is 33.8 cm² and the total perimeter is 31.2 cm.

Area of each basic shape before the Boolean composition.
How to find the area
Area formula: A = 5·l² · 2p = 12·l
Split the figure into basic shapes, find each area, add the joined parts and subtract the cut-outs: A = 6.76 + 6.76 + 6.76 + 6.76 + 6.76 = 33.8 cm².
